The guards suggest many climbers are trying to move up the mountain too fast after having a year of. Denali in southern Alaska is 6,190 meters above sea level. So, climbing it requires a high level of skill. Climbers also need to acclimate to high altitudes (海拔), which is not needed for most mountains in the US. The National Park Service recently made a statement warning that many climbers in the Alaska Range are showing signs of inexperience and overconfidence. After reporting no deaths in 2018 and 2019, at least two people have already died on the mountain in 2021. Two others were seriously injured, officials said. Earlier this month, a skier from the state of Colorado died after falling into a very deep cut in the ice. A climber from the state of Idaho was killed by a large falling piece of ice. The guards made their statement after a Canadian climber was seriously injured after falling nearly 305meters. He was not wearing climbing ropes. Other climbers reported the fall. People in a helicopter (直升机) studying mountain ice in the area were able to save the man,park officials said. The Park Service statement named several reasons for the increase in injuries and deaths. They include extreme tiredness, untested body reactions to high altitudes, quickly changing weather, and not bringing the right equipment. In recent years,guards said they have seen more climbers try to make Denali’s top by climbing the 2,134 meters from the final base camp to the top in one day. This is nearly impossible to do except for the most experienced climbers. Experts suggest that climbers take 17 to 2l days to reach the top of Denali. That includes rest days and extra days to wait out bad weather. 1．What does the underlined phrase “acclimate to” in paragraph 2 probably mean? A．Get used to. B．Get tired of. C．Take control of.
